Surrounding the central portion of hub member 5 is a comparatively heavy, annular disc-like member or ring 'I which is provided with suitably positioned perforations to permit of the attachment of novel traction lugs to beliereinafterfully described.

'Ihe novel wheel,v as illustrated, comprises For the purpose of adjustably securing lugs Illl a cylindrical hub member 5 which has an annular I tov rim 'I the latter is provided with three series external flange 6 adjacent each endthereof, said of perforations or holes I8, I9 and 20 at different ilanges preferably being integral with and, hence, radial distances from the center of the wheel and anges i6 of the traction lugs are provided with a plurality of bolt holes 2|. Preferably, alternate lugs are circumferentially spaced from one another vabout the periphery of the wheel and are secured to rim-'I by means of bo1ts 22 which ex- 55 tend through rim 1 parallel to the axis of hub 5. The holes in rim 1 and in lugs I4 are so spaced that the latter may be removably secured to the former in each of at least three positions by two bolts 22. As shown at the bottom in Fig. 1, bolts 22 extend through holes I8 and 20 in rim 1 and through holes 2l in lugs I4 which register therewith, thus causing an end portion of each lug t0 extend beyond the periphery of the rim at an angle of approximately 30. In the upper left sector of the Wheel in Fig. 1 the inner circle of bolts extend through openings I9, thereby causing an end portion of each lug to extend radially from the periphery of rim 1. In the upper right sector of Fig. 1, lugs I4 are shown secured t0 rim 1 so that both corners 23 of each lug extend beyond the periphery of the rim. In the latter position the ends of adjacent lugs on opposite i sides of rim 1 overlap and a single bolt extending through one of the openings 20 may be employed for securing said adjacent overlapping ends of the lugs to rim 1.

There is thus provided a novelly constructed metallic wheel which is rigid and durable and which has a very high strength factor per unit of weight. Also, the wheel provided by this invention may be very readily and quickly manufactured in large quantities at low cost. Additionally, the construction of the wheel is such that good and proper traction may be obtained in different kinds of soil without danger vof the lugs becoming clogged with sod and hence of no material aid. Novelly constructed traction lugs which may be readily and quickly adjusted to various positions on the wheel or for diierent conditions of operation are also provided.

Although only a single embodiment of the invention has been illustrated and described in detail, it is to be expressly understood that the same is not limited thereto. For example, bolts and nuts may be employed in lieu of rivets I0, I2 or discs 8 may be welded in place on anges 5 and rim 1, if desired. Various other changes may also be made, such as in the design and arrangement of parts illustrated, without departing from the spirit and scope of the invention as the same will now be understood by those skilled in the art. For a denition of the limits of the invention, reference is had primarily to the appended claims.

What is claimed is:

1. In a wheel for tractors and like vehicles, a traction lug having a channel-shaped transverse cross-section and a V-shaped longitudinal cross section the angle between the arms of said V-shape being an obtuse angle less than 180 degrees.

2. A wheel comprising a hub, a disc-like rim surrounding said hub and having the flat surfaces theroef substantially perpendicular to the axis of said hub, means connecting said rim to said hub and traction lugs secured to said rimadjacent the periphery thereof, each of said lugs being channel-shaped in axial cross-section and V-shaped in radial cross-section.
